Syntax

COMAUX1=name

Details

The COMAUX1= option specifies the first auxiliary communication access method. For example, you can specify COMAMID=XMS and COMAUX1=TCP. These specifications indicate that the primary method of communication is cross-memory services. If this access method is unable to establish a connection, TCP/IP communication is attempted.
If the COMAUX1= option is specified in a destination (server) session, it defines additional communication support to be initialized. In an originating (user) session, it specifies that the communication access method should try to connect to the destination session if the initial COMAMID-based attempt is unsuccessful. Because only z/OS has available an alternate communications access method in Version 9 SAS, this option is likely not useful on other host types.
